Orignal No. 1,319,457, dated .an expansion joint ot' the slip-joint typewherein, and among other things, these objects are attained, namely:support et the joint and the line piping; adjnstability of paokinprwithout disasiseinblingl of parts; prevention ot' pnllinr apart ot theSlip-joint onder conditions of extreme vpipe contraction or improperassembling or adjustment oit parts in setting up; the provision ot' ajoint which may be adjusted readily in as- Vseinbling, readilydieasselnbled. repaeked,

ete., without any disturba-nce o'l' the line piping. Other and furtherobjects will be evident from the following speeitieation and claims and:from the annexed drawings, in

It is to be observed here that the stop de- "viee is omitted in Figs. l,2 and 3, because, first, the main. central teatnre'of my invention maybe employed.without any stop means, and, second, beeausetliis form ofillustration affords elearness.

-Specification of Reissue-d Letters Patent. RQSSIIH JHM' ii i Whg)Application for -The two adjacent sections of the line piping; at thepoint where axial movement is to be ta'ken Careof are shown at l and E,the section lubeing threaded or otherwise secured .to or integral withthe flange l. and the Section 2 being' provided with an ordinaryend-flange A short sei-tion oi pipino 5, preferably ot' non-corrosivemetal sneh a: bronze, has threaded yor otherwise sernred to it a Harige6, which flange is bolted to the i'lange t to form a fluid-tight Jioint.The' pipe .fseetion 5 is machined on its outer snrfaee and tits slidablywithin the main body i' of the joint. This; main bodv T has a tlaiwe 8bolted {hdd-tight to the Matige El. and at other end is recessed toreceive the narltino' E) and gland l0. v i In The parts thus desrribed.while in iniproved Ineehanieal t'orzn. are apprimimately those ot; theordinary slip-joint. and with these elements indicated whieh l exnniov imy new combinations, l will now indiiate and describe my improvements.

lhe main body i has an extension flangell. To this llange 11 iS bolted aanida sleeve l2. wbieh is marhined internally and which extends over andmalins a goed sliding joint with the Hannes audio. one or both of whichare machined upon their peripheries. This addition and improvementconstitutes the tiret and main feature ot' my inventioi'l; and it willnow be seen that thirsl gnidwsleeve l2. rigidly secured to the main bodynwmber T and fitting snnglv bnt slidably over the lianges -l am i?, prrrvides a eguide and snpport which prevents sagging of the pipe or ,airainupon or displaeement of the pai-kine iointm-obieen tionable conditionswhich Vhave rendered the ordinary slip-joint undesirable, and theremoval ot whieb rendersl the slip-joint tr'pe ot compensation the mostdefrabie type. l\.oreo\"er7 by re't'erenee to Fig. S esperiallv. it willbe seen that my iinln'oveinent above described not onlyY meets theseobieetions. but atlforda` means of misenihling. di sen .bling andrepaelting without :in v disturbbolts that the gnide-sleeve wonld haveto be ment more laborious but would necessitate such adjustment at thevtime when the support of the guide-sleeve was removed, so that theadjustment might occur with the parts out of perfectalinement, Iprovidey tle main body 7 with the offsets 13, which are bored to-`receive the gland-bolts 14, which vhave their nuts abutting theseoffsets, andthus outside the guide-sleeve, so that the packing may be.adjusted by the'gland as said first mentioned standing flange 1orabbeted flange 18 removal of the guide-r at any time without ld by thesleeve and: while the' parts are he guide-sleeve in perfectI alinement.l

The third main, featurel of my invention, as Kabove indicated, consistsof stop means for preventing pulling apart of the joint under conditionsof undue contraction or improper setting-upg type of slipj oint it isnot uncommon to have the members pull apart and cause 'serious damage.In Figs. 4, 5 and 6 Ivhave shown the preferable form of my improvement.

The guide-sleeve 12 is provided with an outing lugs arranged theguide-sleeve), stops 16 secured thereto by bolts and having theirinwardly-extending, 'or L-shaped, ends across the path of the slidingjoint between the guide-sleeve 12 andthe flanges y4 and 6. In Fig. 4 Ihave shown this feature with the parts in the position when the limit ofpipe contraction permissible at the joint has been reached, and furthermovement at this point prevented by the stops 16 contacting thev flange4.

In Figs. 7 and S `I have illustratedequivalent means for attaining thisen'd which con sist inxcasting the guide-sleeve 12 in two longitudinalparts, provided at its with an inwardly projecting flange 17, whichabout the periphery of crosses the path of the sliding joint between theguide-sleeve and lthe flanges 4 and 6, in al` man1-1er similar A to thestops 16; and at tle other end is provided with a grooved or which takesover the flange 1 1 on the main body '7, and is clamped thereto by meansof sidelugs 19 and bolts 20.' This construction attains the same endsconstruction in Figs. 4, 5 and-.6, and may likewise be removedwithout'removal of the flanges 4. and-6.

.Under some 'conditions this feature of my invention may be attainedVthe simple means shown in Fig. 9, wherein ordinary set-'screws 21 arethreaded through the mdc-sleeve 12 4and extend across the path ofthe'joint between' said sleeve andthe flanges 4 and 6. i

The fourth main feature of my invention arises from the combination andcoperative action of the improvementsabove described,

disposed in said cas1ng,.an annular vhead on' .to form a protectivechamber in which the for with the ordinaryv (or I may use outstand overlwhich are placed free end or adjustment' are effected without di'sturbance of the line piping. I do not wish to limit myself' to the specificlconstructions shown and described, but claim:
